Abstract
Description
Ölmeßstab aus einem flexiblen Bandmetall Oil dipstick made from a flexible strip metal
Die Erfindung betrifft einen Ölmeßstab aus einem flexiblen Bandmetali für ein gebogenes FUhrungsrohr, mit einem Griff und einem Anschlag am einen Stabende.The invention relates to an oil dipstick made from a flexible strip metal for a curved guide tube, with a handle and a stop at one end of the rod.
Es ist ein Ölmeßstab der genannten Art bekanntgeworden (US-PS 3 735 494), der oberhalb des Stabendes einen scheibenförmigen Abstandshalter aufweist. Das Stabende selber ist senkrecht zur Biegeebene abgerundet, in der Biegeebene selbst jedoch scharfkantig. Da das Bandmetall eine bestimmte Steiftgkeit aufweisen muß, um reproduzierbare Messungen zu ermöglichen, kratzt das scharfkantige Ende, wie aus Fig. 2 der Druckschrift ersichtlich, beim Einführen des Ölmeßstabes innen an der Wandung des Führungsrohres in der Außenlinie der Biegung entlang.An oil dipstick of the type mentioned has become known (US Pat. No. 3,735 494), which has a disc-shaped spacer above the end of the rod. The rod end itself is rounded perpendicular to the bending plane, in the bending plane itself but sharp-edged. Since the strip metal must have a certain rigidity, to allow reproducible measurements, the sharp-edged end scratches like can be seen from Fig. 2 of the publication, when inserting the oil dipstick on the inside along the wall of the guide tube in the outline of the bend.
Hiermit sind zwei wesentliche Nachteile verbunden. Zum einen ergibt sich eine Erschwernis beim Einführen des Ölmeßstabes durch Iiangenbleiben oder Verhaken des scharfkantigen Teils, zum anderen können durch das wiederholte Entlangschaben Metall späne abgelöst werden und ins Schmiermittel gelangen.There are two major disadvantages associated with this. For one thing, it results Difficulty inserting the dipstick due to sticking or getting stuck the sharp-edged part, on the other hand, by repeatedly scraping along Metal chips are detached and get into the lubricant.
Der Erfindung liegt die Aufgabe zugrunde, bei Ölmef3stäben der genannten Art eine Anordnung zu schaffen, die ein müheloses wiederholtes Einführen ins gekrümmte Führungsrohr ermöglicht.The invention is based on the object, in the case of oil rods, of the aforementioned Kind of creating an arrangement that allows for effortless repeated insertion into the curved guide tube allows.
Die Lösung hierfür besteht erfindungsgemäß darin, daß das dem Griff entgegengesetzte Stabende zur Führung des Bandmetalls in Biegungen des Führungs rohres einen Kugelkörper aufweist. Hierdurch ist auch bei stark gebogenen und ggfs. auch in mehreren Ebenen verlaufenden Ftihrungsrohren sichergestellt, daß beim Einführen des Ölmeßstabes die Berührung am Stabende stets nur in einem Punkt stattfindet, wobei eine kugelige Fläche an einer konkaven Fläche größeren Krümmungsradius' entlanggleitet. Auch bei großer Steifigkeit des Bandmetalls ist ein Festhaken hier nicht zu befürchten.The solution to this is according to the invention that the handle opposite rod end for guiding the strip metal in bends in the guide tube has a spherical body. This means that even with strongly curved and possibly. also in several levels running guide tubes ensures that when inserting of the oil dipstick the contact at the end of the rod is always only in one point, a spherical surface slides along a concave surface with a larger radius of curvature. Even if the strip metal is very stiff, there is no risk of getting stuck here.
In besonders günstiger Ausführung wird die Kugel durch einen Niet dargestellt, der mit halbkugeligen Köpfen ins Stabende eingesetzt ist. Um zu verhindern, daß ein Abstreifen der Ölmarkierung oberhalb der Kugel durch Kontakte des Bandmetalls mit dem Führungsrohr stattfindet, ist dort erfindungsgemäß zumindest ein Abstandshalter vorgesehen, der in gleicher Art wie die Kugel am Ende als Niet ausgeführt sein kann.In a particularly favorable design, the ball is held in place by a rivet shown, which is used with hemispherical heads in the rod end. To prevent, that a stripping of the oil mark above the ball by contacts of the strip metal takes place with the guide tube, there is at least one spacer according to the invention provided, which can be designed in the same way as the ball at the end as a rivet.
Sofern der blmeßstab zwischen den Messungen dauernd im Führungsrohr verbleibt, ist an seinem Griffende eine Abdichtung vorgesehen, die gleichzeitig dem Festhalten des Ölmeßstabes in seiner Position dienen kann.Provided that the measuring stick is permanently in the guide tube between measurements remains, a seal is provided at its handle end, which at the same time can be used to hold the dipstick in position.
Ein erfindungsgemäßer Ölmeßstab ist in der Zeichnung abgebildet.An inventive oil dipstick is shown in the drawing.
Fig. 1 zeigt eine Draufsicht des erfindungsgemäßen Meßstabes, Fig. 2 zeigt eine zur Fig. 1 senkrechte Ansicht* Fig. 3 zeigt im Querschnitt ein erfindungsgemaßes Detail des Ölmeßstabes.Fig. 1 shows a plan view of the measuring stick according to the invention, Fig. 2 shows a view perpendicular to FIG. 1. FIG. 3 shows in cross section a view according to the invention Detail of the oil dipstick.
In den Fig. 1 und 2 ist mit 1 ein rlexibles Bandmetall gekennzeichnet, an dessen einem Ende eQn ringförmiger Griff 2 in Kombination mit einem Anschlag 3 und einer Abdichtung 4 angebracht ist. Am etgegengesetzten Ende des Bandmetalls t befindet sich ein Kugelkörper 5.In Figs. 1 and 2, 1 denotes a flexible strip metal, at one end eQn an annular handle 2 in combination with a stop 3 and a seal 4 is attached. At the opposite end of the strip metal t there is a spherical body 5.
In Fig. 3 ist im Schnitt das Ende des Bandmetalls 1 gezeigt, das mit einer Bohrung 6 versehen ist. Die Bohrung ist von einem Blindniet 7 mit zwei halbkugeligen Köpfen 8 durchsetzt.In Fig. 3, the end of the strip metal 1 is shown in section, which with a bore 6 is provided. The hole is from a blind rivet 7 with two hemispherical Heads 8 interspersed.
